Google Friend Connect offers a lot of features that are on my To Do list for GaSP. And, I have been keeping GaSP lean and fast in part by leaning on existing packages where I can. At this point, the only code duplication that I have would be the Comment System. It would be deprecated in favor of Friend Connect Comments.
What are your opinions on Friend Connect? I like that it is yet another Google technology for me to master. And, that it would move almost all of the administrative functions over to Google. Then again, I enjoyed writing the Comment System. And, I would be a bit sad to deprecate it.
